摘要: 针对由调速系统引起的弱阻尼低频振荡问题,提出调速侧电力系统稳定器(governor power system stabilizer, GPSS)优化设计方法,在抑制低频振荡的同时确保系统调节速度满足一次调频性能要求。首先,构建GPSS优化模型,该模型以阻尼比裕度与系统达到90%出力时间加权和最大为目标函数,以系统一次调频所要求的速度、稳定时间和稳定性为约束条件;进而,基于粒子群优化算法(particle swarm optimization,PSO)构建该优化模型的求解方法。算例验证了所提模型及算法的有效性及可行性。

Abstract: In order to suppress the low frequency oscillation caused by governors, this paper proposes a new design method for the governor power system stabilizer (GPSS), where the requirement of the regulating speed is satisfied. A new GPSS optimization model was developed in the paper. The objective is to maximize the weighted summation of damping ratio margin and the time of the system to reach 90% load as the objective function, and its constraints include speed and stabilization time of primary frequency modulation requirement and stability requirement. A particle swarm optimization (PSO) based algorithm was developed for the optimization model. Simulation results demonstrate the effectiveness and feasibility of the proposed method.
